A clutch is a mechanical device used in the transmission system of a vehicle. It engages and disengages the transmission system from the engine. It is fixed between the engine and the transmission.
The power produced inside the engine cylinder ultimately aims to turn the wheels so the vehicle can move on the road. The reciprocating motion of the piston rotates a crankshaft by rotating the flywheel through the connecting rod.
The circular movement of the crankshaft is now to be transferred to the rear wheels. It is transmitted through the clutch, gearbox, universal points propeller shaft or driveshaft, differential, and axles extending to the wheels.
With the help of all these parts, the use of engine power for the driving wheel is called power transmission. The utilization of engine power to the driving wheels through all these parts is called power transmission.
The power transmission system is normally the same on all passenger cars and trucks. But its design and arrangement may vary according to the method of drive and type of transmission units.
